Projective geometry primitives for the RustUse geometry workspace.
`use-projective` stores homogeneous coordinate records for projective points, lines, and planes. It
does not attempt deep algebraic geometry.
```rust
use use_projective::ProjectivePoint;
let point = ProjectivePoint::new(vec![1.0, 2.0, 1.0]).expect("valid point");
assert_eq!(point.dimension(), 2);
```
